Backend & Enterprise Job Support
Enterprise backends are complex beasts — distributed systems, legacy integrations, strict SLAs, and multiple teams contributing to a shared codebase. Our backend and enterprise job support gives you a senior architect or engineer to pair with when you hit a wall.
Architecture & Design
- Microservices – service decomposition, communication patterns (sync vs. async), API contracts
- Event-driven architecture – event sourcing, CQRS, outbox pattern, saga orchestration vs. choreography
- Domain-Driven Design – bounded contexts, aggregates, anti-corruption layers
- API Gateway patterns – BFF (Backend for Frontend), rate limiting, circuit breaking
- Hexagonal / Clean Architecture – dependency inversion, testable boundaries
Enterprise Integration
- REST API design – resource modelling, pagination, HATEOAS, versioning strategies
- gRPC – proto file design, streaming types, deadlines, error handling
- GraphQL – schema design, N+1 problem, federation with Apollo
- Message brokers – Kafka (at-least-once vs. exactly-once), RabbitMQ (routing patterns), Azure Service Bus
- ESB / legacy integration – MuleSoft, Apache Camel, IBM MQ bridges
Performance Engineering
- Database query optimisation – slow log analysis, index selection, connection pooling
- Caching strategies – cache-aside, write-through, TTL design, Redis clustering
- Async processing – background jobs, Celery, Sidekiq, Spring Batch, AWS SQS workers
- Load testing – k6, Gatling, JMeter — writing scenarios and interpreting results
- APM – Datadog, New Relic, Dynatrace trace analysis
Observability & Reliability
- Structured logging – correlation IDs, log levels, JSON log format
- Distributed tracing – OpenTelemetry instrumentation across services
- SLI/SLO/SLA definition and alerting setup
- On-call runbooks and incident response
Languages & Frameworks
- Java – Spring Boot, Quarkus, Micronaut
- .NET – ASP.NET Core, MassTransit, Dapr
- Python – FastAPI, Celery, gRPC with grpcio
- Go – net/http, gorilla/mux, gRPC, GORM
